How heat resistant is boron nitride

What is boron nitride?
Boron nitride is typically black, brown or dark red crystals with sphalerite framework as well as great thermal conductivity. Its solidity is 2nd only to diamond, a superhard material commonly made use of as tool products as well as abrasives. Boron nitride has chemical resistance as well as no disintegration by not natural acid and water. The boron nitrogen bond is barged in warm, concentrated alkali. Oxidation begins airborne at 1200 ℃. Decomposition begins at concerning 2700 ℃ in a vacuum cleaner. It is slightly soluble in hot acid and insoluble in cool water. The loved one thickness is 2.29. The compressive stamina is 170 mph. The maximum solution temperature is 900 ℃ in the oxidation ambience as well as 2800 ℃ in the non-active decrease environment, however the lubrication performance is poor at room temperature level. The majority of properties of boron nitride are much better than carbon products. For hexagonal boron nitride: the friction coefficient is superficial Great high-temperature stability, excellent thermal shock resistance, high strength, high thermal conductivity, low development coefficient, high resistivity, rust resistance, microwave or infrared transmission.

What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, progressed refractories and superhard product; splitting up rings for constant horizontal rolling, high-temperature resistant lubes and high-temperature finishes. It is additionally a resources for synthesizing cubic boron nitride. On top of that, it is also a very excellent high-temperature lube, which can be utilized as a part of self-lubricating bearings. Boron nitride has lots of physical properties similar to graphite, called white graphite. It resembles mica, talcum powder, and also silicate; Fatty acids are collectively referred to as white strong lubricants. As a lubricant, boron nitride can be distributed in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface area to form a completely dry film after the solvent volatilizes and afterwards completed the resin, ceramic, and also metal surface layers as a high-temperature immune self-lubricating composite material. It is utilized in aerospace engineering, or the boron nitride powder can be straight coated on the guide rail surface. The boron nitride suspension oil is white or yellow. For that reason, it does not pollute fiber items in fabric machinery and can be extensively utilized in the lubrication of artificial fiber fabric equipment.

Is Boron nitride dangerous to human body?
Boron nitride is not harmful, however boron nitride powder is a cloud of dirt hazardous to human wellness. Boron nitride powder is physically inert and will certainly be detrimental to wellness when swallowed, breathed in, and also exposured to the skin and also eyes. Consuming or inhaling will create skin, breathing system, as well as kidney circulation conditions.

Cost of boron nitride
Boron nitride bit size as well as purity will certainly influence the item'' s price, and also the acquisition volume can likewise influence the price of boron nitride. A large quantity of big quantity will certainly be lower. The cost of boron nitride can be found on our company'' s official website.
